ABSTRACT:
A non-volatile memory device that changes the programming step voltage between the source side of the array and the drain side of the array. After the initial programming pulse, a verify operation determines if the cell has been programmed. If the cell is still erased, the initial programming voltage is increased by the step voltage. The step voltage for the lowest word line near the source line is lower than the step voltage for the word line closest to the drain line.
